You write we should reduce: international shipping, consumerism, and non-essential air travel Sure you can but it will be heavily inconvenient (at least for many in the west). But do you know what reduces the carbon footprint by about 75% in a country like Germany? 1.) Electric cars/trains 2.) Electricity from renewables 3.) Heating using electrical power from renewables (heat pumps) Of the last 25%, there are 20% fr…

I am not disagreeing with electric cars at all, I think it is important. But the carbon footprint created within the West is just a small amount of the carbon footprint that the West contributes to. We can't just reduce our own carbon footprint if it simply pushes that carbon footprint onto other, less developed countries. I think it will be very unlikely that we will continue to live with the same luxuries that we e…

If you freeze the economy to today‘s state and technology, there will be no growth any more, sure. But at least in our lifetime, the move to a sustainable economy will create more growth and opportunities than will be cut in unsustainable industries. I do not what happens in 150 years, but for the next 50 years I do not worry. As we need more intelligent technologies than we used to have, the value ofhe output will rise, thus economies that are able to adapt will profit.

Using solar, wind and water to create power will, by the way, not push the carbon footprint somewhere else. It will, to a great part, vanish. And those economies who, in future, produce their own energy instead of importing them, will have a higher GDP and less dependence of foreign markets.

Yes it is such a shame that the roads are such that when I am on the road with my family some crazy daredevil can't drive 490km/h near us. The roads are for getting from A to B, not racing. If you want to go 490km/h, go to a race track.

Wouldn't you like to reach your destination in a much shorter time than usual? I certainly would.

Yes, because people who want to go 490km/h want to do so because it gets them to B quicker, not because they want to have fun.

Also, no, I'd rather be safe from my own and other's mistakes, which are far more likely to happen at that pace and I'd rather have lower emissions from all cars. I am happy to sacrifice speed for that.

Even if it could be operated safely by a person, it still would have no practical value. This is not a transport feat, it's an engineering/brand feat.

How is it not practical? We have race tracks in my area, so if I owned one of these, I'd get a ton of use out of it destroying other people on the track. That's pretty practical from my perspective. It's not going to make my commute any faster, but that's not the only use for cars.

It wasn’t just tires, but rims as well. If I recall correctly for the original at top speed the useful life of rims was about 30min, tires about 15. You on my had 12 min of fuel at that rate though. Rim + tire replacement was something like 100k USD. Not that anyone was going to be able to put many top speed minutes together in practice.

I recognise James May's delivery of those numbers! https://www.youtube.com/watch?v=LO0PgyPWE3o

I didn't remember that but it must have been what stuck it in my head!

I'm sad that, on HN, I had to read thru 50+ comments about how impractical 300 mph is, before I found any discussion of the engineering challenges.

HN has become extremely negative in the last couple of years. I came over here when I got sick of Reddit's negativity in ~2013. What's the next alternative?

Do you have a source or link to any verified speed runs by those cars? AFAIK those are theoretical numbers, and Koenigsegg has never had a verified run at 300mph+)

I stand corrected, though that is far from a factory car it is still (according to them) road legal. I kinda struggle to see how they are keeping emissions in check wit a 2500bhp engine though.

Somebody told you Ferraris don't have heaters?

I think the actual words was something like “they might as well not have heaters”.

I found a youtube video where someone was testing a Ferrari to see how well the heater worked, compared to a Mini, but once I saw that he was just idling them and not driving them, I decided it was lame and not to link it.

I believe I did point out that on Ninja's (I have one) you need to build the revs; you can't just dump the clutch and go like you can on a BMW Boxer or a Harley (which I also have). Hence the Ninja is generally slowest away when the lights change (but is by far the quickest bike overall). In fact bicycles are fastest off the line, since they produce max. torque at 0rpm (just keep weight on a pedal, release the brakes…

> In fact bicycles are fastest off the line, since they produce max. torque at 0rpm (just keep weight on a pedal, release the brakes to go). I doubt a bicycle would actually cross the starting line before a high end bike or car would surpass it. A 180lb rider would produce about 90lb of torque at most (assuming 6” crank) and that’s only for the instant that the crank is parallel with the ground. A high end car would…

/me commutes by bicycle, 32km each way, in traffic light hell that is Tokyo.

I can get off the line faster then automobiles, they aren't racing / clutch dumping at the lights. Traffic is so heavy and with so many intersections, it's typically pointless for automobiles to race off the line anyways.

As I filter past daily the same Pagani and Bugatti and LFA and Tesla S and NSX. :D
